KSP Forged Upper Control Arm For Silverado Sierra 1500 2007-2018, 2pcs 2-4" Adjustable Front Aluminum Control Arm Fit For Chevy GMC Trucks, One-piece Design Aftermarket UCA With Greasable Ball Joint

These control arms are very light. They fit very well. They have high-quality ball joints that move in every direction and they rotate in their socket. The ball joints are replaceable as well as the control arm bushings where they mount on the frame they have grease fittings on The frame bushings as well as the ball joint on them. They work fantastic. Well worth the price since I bought two pairs of cheap ones and the ball joints for basically frozen and wouldn’t turn in any Direction or turn in their cups this was due to assembly and manufacturing so doing the job twice is never fun. To spend a little extra money and get higher quality like these !!!

good fitment, finish looks nice, easy to install on my customers 2013 suburban with a 2 inch lift

Easy swap from stocks. Used on 2015 Tahoe.

Stock tires rub on them. Adjusting was a pain, alignment was tricky

UPDATE: About 8 months on the happy trails with these KSP's with NO issues. Even after adding another 2" of lift (9" total) and 24" wheels. All I can say is do not over grease the ball joints, and if you have a GM, don't even think about greasing the bushings 🤙 Perfect fit on my 2014 GMC. The video is just a short drive around the block. Anyone who alters the suspension of their half-ton and actually goes off-roading, is crazy. That being said I got these specifically for the looks, and of course, the safety & drive ability of my lift. Most of upstate NY's roads are just as bad as off roading anyway 🤣 GM made the factory UCA outer bushings out of steel for a reason. They are not supposed to be greased. The bushings are supposed to twist for resistance. The UCA is not supposed to slip outside the bushings. And too much grease will make you snap the cam bolts when tightening. I don't have much faith in the urethane bushings, but the ball joint angle is a perfect match for my 7" RC lifted knuckle with a stacked 2" level on the struts. These KSP's are the nice upgrade I was looking for, mostly because my RC crossmembers, LCA's, lifted struts, and sway bar links all support them 💪

Works as intended

Product over seems good BUT ball joint has a small weep hole on bottom it DOES NOT HOLD GREASE.

I bought the a arms about 8 months ago and just got around to installing them, while saving up to re-do my whole front end. Had a major problem. One arm had a side mount for the brake line, other had a top mount that worked with the factory bracket. I think I got one old design, one new design. Amazon thankfully let me return them and reorder. New ones matched and went in easily, ball joint went right in even with 3 inch lift coils. I did notice they do not touch the frame at full droop, the RC I had replaced did. Overall quality is great, black caps are cool and pressed in easily by hand. Awesome to keep ball joints and grease zerks clean. Also, second set ball joints had a grey antitrust coating on the studs, older set did not. I also contacted KSP about instal and these do not need to be tourqed at ride height like rubber ones do because the steel axle shaft is not attached to the poly bushings. The shaft is black powdercoat I think, shouldn't rust. The only thing I didn't like was the brake mount hardware was black and would definitely rust, replaced with zinc coated bolts. The arms themselves are very nice raw aluminum. Truck feels great now. Would recommend, but MAKE SURE ARMS MATCH. The ones with black caps should have the brake line mount hole on top, not side. 2011 Silverado 1500 LT 4x4, 3 inch Fox coils.
